ABSTRACT:
A unitary system for removing particulates from the exhaust gas of an internal combustion engine includes a main flow passage and a by-pass flow passage for conducting the exhaust gas from an inlet portion to an outlet portion of a housing which contains the system. A valve for selectively directing the exhaust gas through one of the passages is provided, with a particulate trap mounted in the main flow passage for trapping particulates within the exhaust gas when the exhaust gas is directed therethrough. A regeneration system is positioned intermediate the valve and the particulate trap with an oxidation catalyst being positioned downstream of the particulate trap and in both the main flow passage and the by-pass flow passage. Further, a control system is provided for selectively activating and deactivating the regeneration system in response to predetermined operating conditions of the unitary system.
